i have approx. 5500 sq. ft. of concrete. its about 1 yr old. a sealer was
put on it after it was poured, but the surface seems to absorb water. i am
considering using a penetrating sealer on it but i am concerned about the
original sealer. do i need to make sure the old sealer is off? if so how
do i remove it? i have a 2500 psi pressurer washer, will that do the
trick? i need your advise. also can you recommend a good sealer? i've
seen some that say you only have to apply it 1 time and never again, is
this true?
I NEED YOUR ADVISE!!! THANKS, JOHN
Concrete Driveway Sealer Video
VIDEO SUMMARY
Concrete driveways are great, but you do not always know if they will installed correctly. In the Tri-state area, a concrete driveway that was installed properly will withstand anything Mother Nature throws at it. But if it was not properly installed or if you are not sure, you better seal it. You can easily apply an application of a silane - siloxane sealer.
First, clean the driveway, brush off all the loose material and be sure it is dry. Be sure to purchase the right sealer. Look on the label for the words silane/siloxane and water repellent. Do not buy silicone sealers. They are bad because they form a film on the surface that does not breathe.
Get a sprayer with the a hand pump. Pour in the sealer and completely spray the driveway. The sealer will dry clear and not change the color of the concrete. It is a simple job. Maybe not as easy as Tim is demonstrating. (Watch the video.)

Without knowing what sealer was used the first time, it is impossible to be
certain about removal. It is my feeling that if water is easily flowing
down into the slab, the sealer is not doing its job and a penetrating
sealer will be able to flow down into the slab and get the job done!
There are a few different penetrating sealers out there, and after a lot of research I believe the silicate reactive sealers are going to protect better than any other type. They are waterborne, colorless, penetrate deep into the slab and fill the pores completely while allowing the concrete to breathe. Salt, water and ice will no longer be a problem at the surface or deep inside. Visit http://CreteDefender.com to learn more about permanent concrete protection. And, yes- you only have to apply it once... ever!

How long should a newly poured driveway need to cure before putting on the
sealer
